Greece taxes residents on worldwide income and non-residents on Greece-source income only. Greece operates an administrative assessment system taxpayers submit a return, and the tax administration calculates and issues the final assessment (ekkathiristiko) determining the liability.
The Greek tax year is the calendar year. The individual filing deadline typically falls in the summer of the following year (commonly cited around the end of June or July), with the exact date confirmed annually by the Greek tax administration (AADE) and subject to change - confirm the current year's specific deadline directly.
Greece's headline corporate income tax (CIT) rate is 22%.
The headline personal income tax (PIT) rate is marginal 44%.
The standard VAT/GST (or equivalent consumption tax) rate is 24%.
An individual is a Greek tax resident if their habitual abode - present in Greece for more than 183 days within any 12-month period - or center of vital (personal, economic, or social) interests is in Greece; residency is deemed to run from the first day of presence once the 183-day threshold is crossed. An exception excludes the 183-day test where a stay is solely for tourism, medical treatment, or similar private purposes and does not exceed 365 days. Residents are taxed on worldwide income; non-residents only on Greece-source income.
A non-Greek entity has a Greek permanent establishment through a fixed place of business or a dependent agent habitually concluding contracts in Greece on the entity's behalf, following the OECD Model Treaty definition as applied under Greek domestic law and any applicable tax treaty.
Greece's CFC regime (recently updated to align with EU ATAD) applies to both corporate and individual Greek tax residents holding a controlling interest (generally 50%+, directly or indirectly) in a foreign legal entity or foreign permanent establishment meeting specified conditions cumulatively (low effective taxation and passive-income composition, among others). Where triggered, the CFC's non-distributed income is included in the Greek resident's taxable base - for individuals, taxed as business income on the individual return. Foreign tax already paid by the CFC (and by intermediate associated entities in indirect-ownership chains) is creditable against the Greek tax due, capped at the Greek tax attributable to that income, to prevent double taxation at multiple levels. Greece is among the group of European countries whose CFC rules tax only the CFC's passive income rather than its full income.
Greece has no formal debt-to-equity ratio; interest deductibility instead follows an ATAD/BEPS Action 4-based interest limitation rule under Article 49 of Law 4172/2013. Net borrowing costs exceeding EUR 3 million are deductible only up to 30% of EBITDA; costs above that threshold are non-deductible in the current year but carry forward for five years.
Greece does not use an elective check-the-box classification system; entity classification generally follows the entity's actual legal characteristics. Greece has implemented ATAD2-aligned anti-hybrid rules denying deductions for payments producing a hybrid mismatch outcome.
No foreign bank account or foreign financial asset reporting regime exists in Greece requiring residents to separately disclose foreign accounts; foreign income is reported through the standard annual tax return.
Greece provides a participation exemption for qualifying dividends and capital gains implementing the EU Parent-Subsidiary Directive: a Greek company holding at least 10% of an EU subsidiary's capital for a continuous minimum 24-month period is generally exempt from Greek corporate tax on dividends received; a domestic participation exemption also applies more broadly to dividends between Greek companies.
Greece has a real foreign tax credit regime for both individuals and companies for foreign tax paid on foreign-source income also taxed in Greece, capped at the Greek tax otherwise due on that income.
Greece has signed 57 double tax treaties. Notably, Sweden terminated its tax treaty with Greece without a replacement agreement currently in place, per the European Commission's tracking of EU treaty developments - confirm current status with the Greek tax authority (AADE) before relying on Swedish-Greek treaty relief.
